PPC 440 series CPUs like the one in the SAM 440 were developed in FPGAs originally. They were glacially slower than the Vampire 2 is when running the 68080. Consequently, if the 68080 were remade as an ASIC (regular masss-produced fast chip) it would probably be faster than a SAM 440 of the same clock speed. It might even be fast enough to run a PPC emulator to run the newer PPC stuff in much the same way as the Intels run OS 4 on WinUAE.
